DSC WS4985 Wireless Flood Detector



New to the DSC family of wireless sensors, the WS4985 Flood Detector is a wireless detector designed to work with the Alexor Wireless Panel as well as DSC 1-Way Wireless Receivers (see Compatibility List for further details). The WS4985 Flood Detector senses the presence of water in basements, laundry rooms, bathrooms, kitchen and numerous other areas where water may leak or flood, prompting advance warning of potential flooding.


The WS4985 is a 1-way wireless transmitter consisting of a probe connected to a wireless transmitter via a 6-foot (1.82 m) wire. The transmitter is installed at a higher level on the wall with the probe located at floor level or a desired height. In the event that there is a water leak, the probe will detect the moisture and deliver the information to the transmitter on the wall.


The wireless flood detector is based on the WS4945 wireless door/window contact that is connected to a water probe through a 6 foot-wire. The product is enrolled as a flood zone detector with the following DSC control panels: Alexor, PowerSeries 9047, PC1616, PC1832, PC1864, PC4020, and is fully supervised.
